Code

protected function assetDiff(array $assets, array $start_assets, $diff_function) {
  $diff = $diff_function($assets, $start_assets);

  // Clean the resulting array up, since backdrop_array_diff_assoc_recursive()
  // can leave half-populated arrays behind.
  foreach ($diff as $key => $entry) {
    // If only the weight was different, we can remove this entry.
    if (count($entry) == 1 && isset($entry['weight'])) {
      unset($diff[$key]);
    }
    // If there are other differences, we override with the latest entry.
    elseif ($entry != $assets[$key]) {
      $diff[$key] = $assets[$key];
    }
  }
  return $diff;
